As trees along a heavily shaded stream are cut down for farm land, the environmental protection agency (epa) must measure changes to the local stream habitat. water samples from the stream are collected over time. the microorganisms are counted and classified in order to track changes.
epa researchers most likely used a to view the microorganisms in the stream water samples.
a)
light microscope
b)
magnifying glass
c)
computer simulation
d)
scanning electron microscope

A)light microscope

Explanation:The EPA researchers would use a light microscope to count and classify the microorganisms present in the stream water samples. A magnifying glass would not be strong enough; a scanning electron microscope would be too powerful. A computer simulation does not analyze real data.

i think its the first one

well, since there is no answer choices, i will give an answer on how it works : )

the two objects are placed together. energy will always be transferred from the hotter object to the cooler object until they are equal. hope this is close to one of the answer choices : )
